I have a Sony Bravia KDL-40V4100. When I select any other picture mode than vivid it will revert back to vivid. So if I am watching a DvD and have selected cinema picture mode I have to constantly hit the picture button on my remote in order to prevent it from defaulting to vivid. It seems to me that if I select cinema it should stay there until I select another mode. It doesn't matter if I select custom, standard or cinema it will revert back to vivid in less than five minutes. Has anybody else experienced this problem
